The Korg Polysix was released in the early '80s around the same time as the Mono/Poly, and shares the same look and feel. However, unlike the Mono/Poly, the Polysix is a true six voice polyphonic synthesizer with patch presets. The voice structure features a single oscillator, envelope generator, VCF, and VCA. An arpeggiator and lush chorus round out the synth.
